Air cleaning apparatus with a moist filter

Abstract

An air cleaning apparatus with a moist filter is disclosed. More particularly, the present invention relates to an air cleaning apparatus with a moist filter, being operated such that: water stored in a bottom reservoir tank flows upward in a centrifugal manner; water molecules are finely cleaved in a microfine state and injected through multiple injection holes in the same centrifugal manner to become moist; under such conditions, water flowing into a rotational column, to which a centrifugal force is applied, is filtered while circulating a cycle wherein external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling ultrafine dust as well as fine dust to be filtered with high efficiency and excellent economic advantage.

What is claimed is: 
     
       1. An air cleaning apparatus with a moist filter, comprising:
 a lower body defined in a barrel shape, the lower body having a reservoir tank at a bottom of the lower body; 
 a rotational column rotatably coupled at a predetermined portion in a center of the lower body, the rotational column being configured to lift water stored in the reservoir tank upward in a centrifugal manner and configured to scatter the water to have a moist layer; 
 a screen barrel coupled to a top portion of the lower body, the screen barrel enclosing an outer part of the rotational column; and 
 an upper body coupled to the top portion of the lower body, the upper body enclosing an outer part of the screen barrel,
 wherein the upper body has a rotational fan configured to exhaust internal air to an outside and a motor disposed at an inner center of the upper body, the motor being coupled to the rotational fan, and 
 wherein the upper body includes multiple air vents disposed on a top surface of the upper body, 
 wherein a top end of the rotational column is coupled with a bottom end of the rotational fan by first and second couplers, and the motor is thereby configured to simultaneously rotate both the rotational column and the rotational fan by rotary power of the motor. 
 
 
     
     
       2. The apparatus according to  claim 1 , wherein an air input-punch band is disposed on top of the lower body and wherein multiple air input holes are punched through the air input-punch band. 
     
     
       3. The apparatus according to  claim 1 , wherein the upper body further includes an operational panel which has a power button, a speed set-up button to set a motor revolution rate (‘rpm’), and a water shortage indicator LED to indicate lack of the water stored in the reservoir tank; and
 the reservoir tank further includes a water level sensor to detect a low level of the water stored in the reservoir tank. 
 
     
     
       4. The apparatus according to  claim 1 , wherein the rotational column is configured to lift the water in the reservoir tank upward while rotating, the rotational column including:
 a water supply vessel that has water input holes punched at a predetermined portion on a top end of the water supply vessel, the water supply vessel having an engaging shoulder defined around an outer periphery in a middle part of the water supply vessel, to which an injection column is coupled and engaged; 
 the injection column that is engaged around an outer periphery on an upper part of the water supply vessel, the injection column having multiple injection holes defined on the injection column; and 
 a top cover coupled to the top end of the water supply vessel to fix the injection column, 
 wherein an additional reservoir is disposed between the water supply vessel and the injection column, and a water supply pipe is disposed to pass through a bottom surface of the water supply vessel wherein a top end of the water supply pipe is bent in a ‘┐’ shape. 
 
     
     
       5. The apparatus according to  claim 1 , wherein the screen barrel includes:
 a receiver defined in a circular band shape around an inner periphery on a bottom of the screen barrel, wherein the receiver is configured to receive sprayed water falling along the inner periphery; and 
 a guiding track connected to the receiver to guide the sprayed water toward a center of the reservoir tank. 
 
     
     
       6. The apparatus according to  claim 1 , further including a filter configured to purify water, the filter being disposed at a predetermined portion in a center of reservoir tank wherein a bottom end of a water supply pipe is inserted into and housed in the filter. 
     
     
       7. The apparatus according to  claim 4 , wherein a gap between the water supply vessel and the injection column is 0.5 mm. 
     
     
       8. The apparatus according to  claim 4 ,
 wherein the multiple injection holes are aligned and punched alongside one another, the multiple injection holes defining a straight injection-hole line, 
 wherein the straight injection-hole line has three injection-hole lines that are spaced apart from one another, the three injection-hole lines defining an injection group, and wherein a plurality of injection groups is defined on the injection column. 
 
     
     
       9. The apparatus according to  claim 8 , wherein the multiple injection holes are punched in a diagonal line at a predetermined angle, and injection-hole lines are aligned in parallel to one another.
